Title: 
STS-26 Discovery, OV-103, flight readiness firing (FRF) at KSC LC pad 39B
Description: 
The flight readiness firing (FRF) of STS-26 Discovery's, Orbiter Vehicle (OV) 103, three space shuttle main engines (SSMEs) is successfully conducted on Kennedy Space Center (KSC) launch complex (LC) pad 39B. The flames of the SSME firing, an immense exhaust cloud escaping from the under the launch pad, and the retracted rotating service structure (RSS) are visible in the view. Six days earlier the firing countdown was halted inside the T minus 10 (T-10) second mark, just prior to SSME ignition, due to a problem in SSME number 2 propellant bleed valve. The approximately 22 second firing was conducted to evaluate the performance of various components of OV-103, external tank (ET) and solid rocket boosters (SRBs), as well as the launch facilities and support equipment which will be used during the launch of STS-26. Two of OV-103's SSMEs have never flown before - engines in the number 2 and 3 positions. SSME number 1 has flown three times and has been through a previous FRF. View provided
